ЧТО ОЗНАЧАЕТ СЛОВО TAILINGS
шлам
Хвостохранилища, также называемые шахтными отвалами, кукурузные отвалы, шламы, хвосты, отходы, выщелачивающие остатки или пятна, являются материалами, оставшимися после процесса отделения ценной фракции от неэкономической доли руды. Хвосты отличаются от вскрыши, которая представляет собой отходную породу или материалы, лежащие над рудой или минеральным телом, которые перемещаются во время добычи без обработки. Добыча полезных ископаемых из руды может быть осуществлена двумя способами: добыча россыпей, которая использует воду и гравитацию для извлечения ценных минералов или добычи горных пород, которая использует измельчение породы, а затем химикаты. В последнем случае добыча полезных ископаемых из руды требует, чтобы руду измельчали на мелкие частицы, поэтому хвосты обычно небольшие и варьируются от размера песка до нескольких микрометров. Шахтные хвосты обычно производятся на мельнице в виде суспензии. В некоторых ситуациях хвосты представляют собой внешние затраты на добычу полезных ископаемых. Это особенно справедливо в отношении ранних операций по добыче полезных ископаемых, которые не предпринимали надлежащих мер для обеспечения безопасности окружающей среды после закрытия.
Значение слова tailings в словаре английский языка
Определение хвостов в словаре - это отходы, оставшиеся после определенных процессов, например, из рудообрабатывающего завода или измельченного зерна.
